Tens of thousands of coyotes are killed by the government and hunters annually. But coyotes, as coy as their name implies, seem more scared than aggressive when confronted. Attacks are rare, Brown said, and often happen when humans feed them, which is illegal. According to one study, about a dozen coyote attacks occurred each year between 1985 and 2006. In contrast, about 4.5 million dog bites are reported every year, according to the Centers for Disease Control and Prevention.
